So, how do you know that you have finished building?... That this build is as complete as it's ever going to get?
When you strum a guitar I find quite often I can actually feel the vibrations in the body of the guitar with my chest. Even just an open string strum there are times that with both palms on the body I can sense it resonating and vibrating to the open chord...
And that's where I'm at with this build. I mocked it up with the intent of stripping it down again to finish the back, as in either some Tru-oil or some form of gloss, but I can't bring myself to do it because I'm so impressed with how it plays and resonates.
You can dismiss me being over-awed on the fact it's a 12 string because I have a 12 string acoustic that did the whole 'Wow, 12 strings' thing to me years ago.
Leaving it as it is with just sanded shellac on the back is way beyond temptation... I had a fiddle with the string heights so all are now set at 2.0mm on the 12th fret, and loosened the truss rod 1/3 of a turn, haven't even considered checking the intonation, and I'm super happy with how it plays and how it sounds electrically and acoustically. Hmmm, I'm starting to have thoughts that this build is done...
